Jeff took 5 weeks to compete and is a simple IC robot. Jeff's main thing is the led headlights witch come on automatically when it is dark. It works by having what is called a current see sore witch when the current is higher on the Ldrs side compare to the Variable resistors side it puts power to chip (Ua741) then puts power to the transistor (BC109)  then to the Leds. Jeff is simple to make but fiddle as you can see he is made from a sandwitch tub,If you what instructions please leave a comment below. 
<p>i would love a step-by-step for Jeff please.</p>
<p>Would be interest to build this with Scouts as part of the Robotics Badge</p>
It would be great if u could send me the schematic diagram as well@anmolsaxena999@gmail.com
<p>can you please send me the circuit diagram??</p>
Cool! I want to build it and it would be awesome if there were instructions.
<p>please! You can send me step by step how to make jeff with BOM instructions. migueletorrec@gmail.com</p>
<p>certainly i need instructions. Which IC to use?</p>
<p>The microchip is UA741 </p>
<p>Can u please give me the instructions</p>
can i you send me a message with the circuit and other things ? thankyou
okay I'll sent the circuit diagram <br>and pcb
We <em>absolutely</em> need a step-by-step instructable for Jeff!
<p>I am starting a news letter about what I'm doing if you want to receive it please reply <br><br>P.S I have released a step by step for jeff<br></p>
<p>I'm replying</p>
Great <br><br>I'll send it right to you <br>Do you still want a step by step for Jeff
<p>I think we all do!</p><p>(How are you sending the newsletter? By PM?)</p>
Out of ingested what is PM?<br><br>And at the moment I'm sending them just as a private message<br>I think I sent you
<p>Yes, PM is Private Message. I saw the newsletter, I just haven't had to read it yet.</p>
Cool <br><br>hope you enjoy it <br>Please tell me your thought <br>about the next Jeff <br><br><br>
feel free to comment on the news I like to hear what other think of my plans
I am starting a news letter leave a comment if you want to reiceeve it
plese send me the full contents with circuit diagrams. <br>MY ID:iitjeehari@gmail.com
<p>Okay, I am working on it ill send it to you when I am done</p>
I would love to make Jeff. You should make an instructable with more detail...ie step by step instructions.
I agree I would like an instructable
love the idea
